GRAIN-SEPARATOR.

SPECIFICATION formingpart of Letters Patent No. 281,589, dated July 17, 1883.

' Application filed May 4, 1883.

To all whom it may concern.-

Be it known'that I, J OSIAH M. WE BOURN, of Edison, in the county of Morrow and State of Ohio, have invented certain new anduseful Improvements in Grain-Separators; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, which form a part of this specification, and in which V Figure 1 is a perspective view of a portion of aseparator-shoe provided with my improvement. Fig. 2 is a top 'view of the same. Fig. 3 is a bottom view of the same. Fig. 4 is a longitudinal vertical section of the same, and

Fig. 5 is a cross-section of the same.

Similar letters 'of reference indicate corresponding parts in all the figures.

My invention has relation to improvements in separator-shoes; and it consists in the im-- proved construction and combination of parts of the board in the bottom of a separatorshoe, through which the screenings and the seed are removed, as hereinafter more fully shown and described, and'particularly pointed out in the claim. I

I11 the separator-shoes generally used the board covering the opening in the bottom of the shoe, through which the screenings and the wild seed are removed, has been simply made to fit inside the-edges of the opening, and been held in place by turn-buttons; but by this construction there has been the drawback andtrouble, that in dry weather the board would shrink up and allow the grain to be spilled, and in damp weather the board would swell out, so that it could hardly be removed, and if once removed could not be pressed in place again, which has been the source of great loss of time and grain. To avoid "these troubles I construct the opening and the board in the following manner:

In the accompanying drawings, A indicates No'mozlel.)

of which are secured by transverse strips F, of metal, upon the upper surface of the bottom of the shoe, and'the lower screw-threaded ends of which screws are provided with perforated yokes G, of metal, which rest with their ends upon the under side of the frame, and may be brought to bear against the same by thumbnuts H, which fit and turn upon the ends of the screws. 2

In this manner it will be seen that the board may be made small enough to fit easily into the opening at all times, and will still cover the opening so that it will not leak, even if it should shrink considerably, and that the board may be removed with very little trouble and ina moment of time. Having thus described my invention, I claim and desire to secure by Letters Patent of the United States.

As an improvement in separator-shoes, the combination of the bottom of the shoe having the transverse opening, the frame upon the under side, the board smaller than the open-- ing, the screws having the transverse strips securing their heads, the perforated yokes S0 spanning the opening, and the thumb-nuts, as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
